Team work over years Adaptability Based on Science Helped multiple species cross the road The crossings and fences are maintained Photo credit: K Foresman, MDT & MSU

Based on Science Adaptive Management was used in Arizona along SR 260 outside of Payson Different elk crossing designs resulted in knowledge of what worked best, adapted rest of project Note: About 90% of factors that make a crossing successful relate to its placement on the landscape. Have to know where wildlife prefer to move Alberta s Banff National Park The Elk crown had jewel higher repel of wildlife rate to crossing steep systems, walled crossing in large part because of decades of research Photo credit: K.

Tools of Science Cameras to determine wildlife usage of crossings and areas of interest Tracking Photo credits: P. Cramer, USU
Tools of Science Mapping of animal-vehicle collisions & carcass data to determine hotspots Wires to snag hair & then examine DNA Tracking devices to determine where wildlife travel across the landscape and if they use crossings Map courtesy of UDOT Photo credit: T.
